Free serverless URL shortener on Google Cloud Run

Intro I've been using with a custom domain to keep track of and share messy links for a few months now. That approach has worked very well, but it's also seriously overkill for my needs. I don't need (nor want) tracking metrics to know anything about when those links get clicked, and doesn't provide an easy way to turn that off. I was casually looking for a lighter self-hosted alternative today when I stumbled upon a serverless alternative: sheets-url-shortener.
